At the same time, he also noticed that not all of the light dots entered the waste pill; some of them dissipated into the air, which was clearly a waste. So William Clark consciously altered the light dots within his body, gathering them more tightly together so that more of them would enter the waste pill.

Sure enough, the speed of impurity separation increased as well. However, after two or three minutes, with a soft pop, the pill in his palm burst apart.

William Clark opened his eyes and brought his palm in front of him. Lying there was a shattered spirit pill, emitting a burnt, scorched smell. This attempt had ended in failure.

“It seems the blue light dots really can separate impurities and purify the essence, turning waste into treasure.” William Clark muttered to himself, showing no sign of discouragement on his face. Although the experiment had failed, he had gained a lot and confirmed his hypothesis.

Next came the analysis. He reviewed the process of controlling the blue light and found no mistakes. So the only possible reason for failure was the speed—could it be that the light dots entered the pill too quickly, exceeding its capacity?

William Clark made a hypothesis, and to verify it, he had to try again. However, the blue star sea within his body was now too small to support another purification attempt. It seemed he could only rest for a while and try again later.

Chapter 15: Attempts and Insights

After resting for an hour, the star sea within his body had returned to normal. William Clark took out a waste pill, sat cross-legged, and tried again.

Circulation, controlling the light dots to enter the waste pill...

Pop!

Another failure. It seemed the flow of the light dots needed to be even slower.

He rested, then tried again.

This time, William Clark tried to slow down even more, taking it step by step. Haste makes waste—since the light dots entered too quickly and caused the pill to explode, he would just slow down a bit.

However, this time, something unexpected happened. When the light dots entered the waste pill too slowly, not only were the impurities not purified, but they actually moved around inside the pill, becoming even more entangled with the essence, inseparable.

So going too slow didn’t work either.

William Clark played with the failed product, thinking carefully. The purification process was truly hard to master—too fast wouldn’t do, too slow was no good either. He had to control the speed within a certain range to have any chance of success.

But what exactly was that range? There was only one way to find out: repeated experimentation.

William Clark meditated and rested for a while. Once his strength had recovered, he began purifying again. The whole night, he didn’t sleep, resting and trying, working tirelessly to master the secret of the blue light dots as soon as possible.

Darkness was driven away by dawn, and the sun rose.

William Clark held a pill that was pure white all over in his hand. After a night of attempts and wasting another five waste pills, William Clark had finally succeeded in purifying one more.

Recalling the speed at which the light dots flowed during the last purification, William Clark looked thoughtful. After a short rest, he took out another waste pill.

But a moment later, it ended in failure. William Clark shook his head. Although he now understood what kind of speed was needed, his control was still clumsy. There was no other way but to practice—skill comes with practice.

Even so, with his current success rate, he could purify one pill out of five waste pills—a 20% chance, which wasn’t low. Last time, Elder Mason had made things difficult for him, tossing him two bottles of waste pills instead of two spirit pills.

Originally, it was a big loss, but now, with the blue light dots...

There were a hundred waste pills in one bottle. With two bottles, he could purify at least forty spirit pills, which was twenty times more than the original two.

A faint smile appeared at the corner of William Clark’s mouth—not because he had obtained a large number of spirit pills, but because with this blue light dot ability, there was now hope for cultivating immortality. As long as he had the support of medicinal power, even an ordinary person could succeed.

His research on the star sea had yielded preliminary results. What he needed to do next was to continue deepening and mastering it. William Clark pushed open the window. It was already bright outside, time for cultivation. William Clark carefully put away the jade bottle and the purified waste pills, left the room, and went to the Qi Refining Hall of the Young Eagle Pavilion to meditate. Even though he now had the star sea and didn’t have to worry about running out of spirit pills, hard work was still essential.

In the following ten or so days, William Clark diligently cultivated while quietly purifying waste pills. It wasn’t just to obtain the spirit pills needed for cultivation, but also to quickly become familiar with, understand, and fully master the use of the star sea.

After all, this was the hope of going far on his path of cultivation—he couldn’t afford any mistakes!

Having made up his mind, William Clark began to carry out his plan. The process was arduous, like crossing a river by feeling for stones. Holding a waste pill, circulating the blue light, controlling the speed, and carefully observing with his spiritual sense.

Pop!

Another failure. William Clark’s face darkened. In others’ eyes, waste pills were trash, but to him, they could all become spirit pills. So every time he wasted one, it pained him.

But this was the trial phase—losses were inevitable. And besides the consumption of waste pills, the star sea had also shrunk considerably. William Clark had no choice but to rest for a while...
